Paris has a new It couple shaping our image of the City of Light. They’re not actors, like Alain Delon and Romy Schneider, or musicians like Jane Birkin and Serge Gainsbourg. They’re interior designers Charlotte de Tonnac and Hugo Sauzay, both 38.

Under the banner of Festen, the pair have delivered a slew of new hotels across the French capital that range from boho cool to über elegant, in each case creating unique spaces of a timeless allure.
